Head wide and almost flat; with fairly dense and sharply defined, hut rather 

 small punetures, becoming sparser towards base. Eyes lateral and rather small. 

 Antennae scarcely passing base of prothorax, third joint abont as long as first 

 and second combined, or fourth to si\tli combined, ninth and tenth each about 

 twice as wide as long, apex incurved to middle, eleventh slightly longer than 

 tenth, its apex rounded. Prothorax at base about thrice as wide as the median 

 length, base bisinuate, much wider than apex, front angles produced and acute, 

 hind ones rectangular, sides narrowly margined; punctures small and rather 

 sparse. Scutellum wide, almost impunctate. Elytra closely applied to and with 

 outlines continuous with those of prothorax, widest at about basal fourth: with 

 regular rows of rather small but sharply defined ]iunctures; interstices wide, not 

 separately convex, with minute and sparse punctui-cs. Intercoxal process of 

 prosternum subconica.1 in i'roni, Avidc and almost truncate at l)a.se. Abdomen 

 with coxal lines distinct and almost enclosing a plate on each side. Legs rather 

 short and stout ; femora feebly grooved along under-surface. Length, 3 -20-5 mm. 



Hah. Northern Queensland (Blackburn's collection), CooktOAvn (H. J. 

 Carter from H. W. Cox), Babinda (Dr. J. F. 'Tllingworth), Kuranda (F. P. 

 Dodd). Type, L 11786. 



Judged by colour alone the antennae would appear to have a five-jointed 

 club, as the five apical joints are black, but the seventh is much the same shape 

 as the sixth, although a trifle Avider, the eighth is much smaller than the ninth, 

 but as it is much wider than long, with its outer angles triangular, it might fairly 

 l)e regarded as belonging to the clul), and the latter in consequence to be four- 

 jointed. Chapuis notes the club of Tritomn as three-jointed, and in English 

 specimens of T. hipustulata it is cons]ucuously so, but as, in most details, includ- 

 ing the finely faceted eyes, the present species agrees with the characters of that 

 genus, it has been referred to it. It is a Iniefly elliptic, moderately convex 

 species, and of six specimens no two have the elytra of the same shade of colour, 

 although metallic in all ; the specimen, from the Blackburn collection, is slightly 

 narrower than the others, its pronotum is entirely dark, but with a slight greenish 

 gloss, the elytra are purple, and the legs (except the tarsi, knees and trochanters) 

 are blackish. 



EUXESTUS TASMANIAE Lea (formerly TRITOMIDEA). 



Numerous specimens from Victoria (Dividing Range and Mount Hotham), 

 and New South Wales (Glen Innes), appear to belong to this species, but differ 

 from the types in being slightly smaller and with the head and iirothorax almo.st 

 entirely black or blackish. 



Mr. Arrow has stated that Tritoniidid is a synonym of Euxestus.i^)
